Lactic acid, or lactic acid, is one of the most important chemical compounds that play a major role in biochemical processes inside the body, and it is produced primarily from the skin, muscles, and red blood cells, in the absence of oxygen, and is also produced by the cultured bacteria found in milk, giving it The taste is sour, and it is found in different types of fruits. Lactic acid is classified as a carboxylic acid, and its chemical formula is C2H4OHCOOH. The normal level of lactic acid in the blood is about (6 to 18) milligrams, in men, women and children.
The fate of lactic acid in the body
- A small amount of lactic acid is converted to pyruvate, which is then broken down into carbon dioxide and water.
- Most of the lactic acid is converted to glucose, during the process (2 glyconeogenesis), where it is transported from the muscles to the liver, during the Curie cycle, then converted to glucose, and then glycogen, where it is stored in the muscles or liver.
Health benefits of lactic acid
The medical or cosmetic benefits of lactic acid can be taken advantage of, by drinking yoghurt or yogurt, by eating fruits and vegetables, or by using cosmetics enhanced with its extract, and these benefits include:
- It provides the body with energy, as it is considered one of the most important vital compounds resulting from the process of glycolysis, which enters the mitochondria, where it is oxidized during the Krebs cycle, and then the energy compound (ATP) is produced.
- Contributes to lowering cholesterol in the blood.
- Helps dissolve bile salts, and stimulates the secretion of gastric juices.
- It improves the digestion of proteins.
- Promotes absorption of calcium, iron, and phosphorous.
- Facilitates the transfer of nutrients from the stomach to the intestines.
- Inhibits the growth of microorganisms, which are responsible for the putrefaction of proteins.
- Delays the appearance of signs of aging and wrinkles.
- It exfoliates the skin, renews cells, removes spots, improves skin texture, and gives it freshness and vitality.
Industrial Benefits of Lactic Acid
- It is used in many industrial applications as an acidifying agent in beverages, foods, cosmetics, and skin emollient creams.
- It is used as a preservative in food, and in the pickles industry.
- It is used in many medicines, injectable serum used to treat ischemic alkalosis as a source of bicarbonate, as well as in vaginal suppositories used to treat candidiasis, and in topical ointments used in the treatment of warts.
High level of lactic acid in the blood
The level of lactic acid in the blood rises as a result of an increase in the speed of glucose metabolism during great physical exertion, or as a result of low blood oxidation, or as a result of insufficiency in the functioning of the liver, or taking certain types of drugs, which leads to acidification of the blood, and damage to many systems and organs of the body .
